Structure of Pneumatic Supply Plate Data
with UA-OFF Monitoring Board
The electrical UA-OFF monitoring board transfers all signals including the supply voltages.
The UA-OFF monitoring board recognizes whether the UA voltage falls below the UA-OFF value.
8.1
Process data
The electrical UA-OFF monitoring board does not have process data.
8.2
Diagnostic data
The UA-OFF monitoring board sends a manufacturer-specific diagnostic message to the bus
coupler, which indicates that the actuator voltage (UA) is too low (UA < UA-OFF).
The diagnosis is structured as follows:
In the User Structure Identifier (USI) (first 16-bit value), the slot number is coded and 0x0040 is sent
in the diagnostic data (second 16-bit value). This corresponds to a group diagnosis.
If several diagnoses are available, for example if a short circuit is detected in several modules,
each diagnosis is set and also reset individually.
8.3
Parameter data
The electrical UA-OFF monitoring board does not have parameters.
